To Build an MD5 encrypted password in C#

   Md5 is a good algorithm for securing your passwords
thanks to .net that it has a wonderful namespace  System.Web.Security which contains built-in functions for all well known security algorithms.
The code to obatain an MD5 encrypted string from any given input is as follows.  

  public string getmd5hash(string input)
        {
            MD5 md5hasher = MD5.Create();
            byte[] data = md5hasher.ComputeHash(Encoding.Default.GetBytes(input));
            StringBuilder sBuilder = new StringBuilder();

            for (int i = 0; i < data.Length; i++)
            {
                sBuilder.Append(data[i].ToString("x2"));
            }

            return sBuilder.ToString();

        }
